There is symmetry and there is not symmetry.There is no "rough" symmetry just as there is no roughly being heterosexual. There is straight, bi, gay, neuter, or good red herring..If you do not speak precisely - outside of the quantum milieu - in science, well, that's the sort of unfortunate result of teaching science on television.
There is no transformation of the image of a sponge which reproduces the image.
The Phylum PoriferaEtymology:- From the Latin porus for pore and Ferre to bear, hence an animal with with pores.Characteristics of Porifera:- 1)No definite symmetry. (my emphasis)2)Body multicellular, few tissues, no organs. 3)Cells and tissues surround a water filled space but there is no true body cavity. 4)All are sessile, (live attached to something as an adult). 5)Reproduce sexually or asexually, sexual reproduction can be either gonochoristic or hermaphroditic. 6)Has no nervous system. 7)Has a distinct larval stage which is planktonic. 8)Lives in aquatic environments, mostly marine. 9)All are filter feeders. 10)Often have a skeleton of spicules.

(1)I repeat .. "A geometric shape or object is symmetric if it can be divided into two or more identical pieces that are arranged in an organized fashion. Can you do that with the images I showed?"...(2) I was taught how to put my case more strongly than that at Stanislaus State College, Turlock, California.
The question of the most asymmetrical animal - which happens to be the matter at hand - depends upon a clear and rigorous definition of symmetry or everything else said is nonsense.
Still up to their shoddy tricks I see. I am posting this after they removed it. (Although I did instantiate one of my cyber golems to post it originally.) As you can see from this, it terrifies certain people. Anybody want to make a side bet on how often this stupidity is repeated? (Hint: golems are very easy to instantiate ..."ad nauseum" here )+++++++++++++++++++++++++++++Well played, Oxford!"Bored_Chemist" is many things, but a Clown? Funny?Pecos_Bill wise up!But I wonder why you (Bored_chemist ) find it your personal mission in life to follow him continually about and hector him?This thread began on September 16th. It lay here peacefully until the 23rd when Pecos_Bill had the temerity to make his opinion known at 3 AM.You, Sir, showed up at 9AM that day to contradict him after seven days in which you had not enough interest to speak at all. This same behavior was seen in the notorious GCSE dogfight - now locked away as too radioactive to be entered anymore.This is the sort of thing that gives people nightmares about nuclear weapons in England. You see what you precipitated here ... over an obscure point of biology.Here are a pair of concepts for you to meditate upon.1. Live and let live.2. Mind your own damned business.For as Rodney King said - As the smoke was clearing in the LA riots, "Can't we all just get along?"ADDENDUM: Because if you keep this up one of us has to go. And they can't keep me out.
